is it possible to be timid and still be considered a "man in the arena"

Yes, it is possible to be timid and still be considered a "man in the arena." Being a "man in the arena" refers to someone who is actively engaged in life, taking risks, facing challenges, and striving for their goals despite their fears or limitations. Timidity or shyness does not necessarily preclude someone from being in the arena, as long as they are still pushing themselves outside of their comfort zone and actively participating in the world around them. It is not about the absence of fear, but rather the courage to act in spite of it.
